Right now I am using:


I want to know if there is a better way for getting the post id that consumes less resources?

An alternative to your way would be to access the $post global:

global $post
echo $post->ID;


  1. It won't make a noticeable difference, either way
  2. If you want to increase efficiency, you ought to be looking elsewhere...

EDIT, pertaining to comments:

what about get_the_ID();?

--> Needs to be run inside the Loop.

i have tried both options (get_the_ID and accessing $post global) both give me a wrong id.

If the latter is the case, you, or some plugin you are using, has not properly reset postdata.

You say to look elsewhere... where should I be looking?

I have no idea what it is you are writing. But if you experience resource bottlenecks or inefficiency, retrieval of the current post ID is likely not the cause.

  • just checked, so I can safely keep using $wp_query->post->ID; ? And, if I want to use your way, I can put <?php wp_reset_postdata(); ?> before global $post

  • Well, the resetting of the post global should happen after whatever secondary loop modified the global. But essentially, yep, your above assumptions are correct. Sep 17, 2013 at 22:05

You can also use get_queried_object_id() in conjunction with is_main_query() outside the Loop

if ( is_main_query() )
    $mypostid = get_queried_object_id();

Note that this function will return author id on a archive page, category id on a category archive, etc.
